What is known as intellectual montage was originally the fifth of the methods outlined by Sergei Eisenstein in a 1929 text. The Soviet director mentioned the following categories: metric montage, which takes into account the identical length of a group of shots; rhythmic montage which in response to the internal movement in the frame generates sequences of shots that appear to have the same duration; tonal montage, where all the shots in a sequential block reflect a single "emotional tone or sound"; overtonal montage, where a group of shots with a dominant visual motif is combined with groups of shots with other motifs, as in a piece of music for several voices; and intellectual montage, which Eisenstein defined as "intellectual harmony", a category of greater complexity in which the dominant voice expressed in one or more shots may differ considerably from the rest, colliding with one or more other shots so that the audience seeks and finds the meaning of that harmonious association that sometimes reaches symbolism or metaphor.
The legacy of the intellectual montage of Eisenstein can be found in counterpoint sequences such as the initial block of Hiroshima mon amour, of Alain Resnais, with voice-over of the lovers on the documentary images of the effects of the atomic bomb on the inhabitants of Hiroshima
In "Manifesto for Orchestral Counterpoint", from the early years of sound film, the signatories Sergei Eisenstein, Vsevolod Pudovkin and Grigori Aleksandro proposed a concept similar to intellectual montage but instead of associations of images they talked about a mismatch between image and sound, simultaneously seeking complementarity and avoiding repetition as a way to add information. The audio-visual counterpoint is a derivative of intellectual montage and represents one of the most ambitious ways to transmit information. Eisenstein put this into practice in some points of Battleship Potemkin (Bronenosets Patyomkin, 1925) and in numerous sequences in October: Ten Days That Shook the World (Oktyabr, 1928). The legacy of Eisenstein's intellectual montage can be found in counterpoint sequences such as the initial block of Hiroshima My Love (Hiroshima Mon Amour, 1959) by Alain Resnais, with the voiceover of the lovers heard over the documentary images of the effects of the atomic bomb on the inhabitants of Hiroshima, and in Her (2013) by Spike Jonze, in various sequences such as the one with the protagonist having sex with a girl whose voice is that of the operating system he has fallen in love with.
Léolo
Léolo / Léolo | Jean Claude Lauzon, 1992, Canada/France.
Léo Lauzon is a child who lives in a poor district of Montreal, trapped in a squalid existence. Every night he tries to escape through memories, dreams, reading and his boundless imagination, but the harsh reality of the family always interrupts his fantasies: he has a father obsessed with the intestinal health of the whole family, a bodybuilder brother who is a prisoner of fear, two sisters suffering from mental disorders, a psychopath grandfather and a hugely courageous mother who tries to control such dysfunctional domestic microcosms as best she can. In such an environment, Léo comes to believe that he owes his existence to a fortuitously fertilised Italian tomato. From that moment he decides to call himself Léolo Lozone.
